Definitions

  • the invention relates to a delivery device, by which small parts in the nature of studs, bushes and pins are delivered to a transportation channel from a sloping collection area, with a retaining and dividing wall, which stands approximately perpendicular, on one side of which the sloping collection area ends in an aperture at a distance from the retaining and dividing wall and along the other side of which is the transportation channel running at an incline to the horizontal, and with a strut in the form of a plate, also displaceable approximately perpendicularly along the retaining and dividing wall, which in its lower position is located approximately at the height of the end edge of the sloping collection area and in its upper position above the transportation channel, in such a way that small parts coming to rest on the retaining and dividing wall are carried along by the upper narrow side of the strut and are delivered into the transportation channel over the upper edge of the retaining and dividing wall.
  • a delivery device of this kind is known from operational practice.
  • the small parts such as studs, bushes and pins arrive on the sloping surface from a magazine and come to a halt at the retaining and dividing wall still in a largely random arrangement.
  • the strut travels upwards at regular intervals and takes the small parts located on its upper narrow side with it.
  • the small parts located on the upper narrow side are by this time substantially aligned in their longitudinal direction.
  • a side infeed conveys the small parts over the upper edge of the retaining and dividing wall into the transportation channel located on the other side.
  • the receiver profile of the transportation channel i.e.
  • the shape of its cross-section is often a segment of a circle, the measurement of which approximately corresponds to that of the small parts to be transported.
  • the small parts then slide in a kind of flat channel or trough, wherein the transportation channel vibrates. They are delivered therein to an application site.
  • the known delivery device is not free of defects. For instance, during the lifting movement of the strut individual small parts often fell back on to the sloping collection area in an erratic fashion. Or they were not reliably delivered to the transportation channel at the highest point of the strut. It had also proved desirable to be able to meter the exact number of small parts arriving in the transportation channel from the sloping collection area. This is the way to achieve as even a supply to the transportation channel as possible.
  • the object of the invention is therefore to create a delivery device of the kind initially mentioned, by which the small parts can be delivered to the transportation channel from the sloping collection area reliably and in amounts which can be exactly determined.
  • the delivery device is characterised in that the upper narrow side of the strut slopes diagonally downwards at least partially towards the retaining and dividing wall.
  • the obliquely designed upper narrow edge prevents the small parts from falling down and they roll with no further ado from the narrow side down into the transportation channel when the upper edge of the retaining and dividing wall has been passed.
  • the delivery device according to the invention therefore works very reliably and it can be expected that the small parts, having reached the oblique upper narrow edge of the strut, will be reliably delivered into the transportation channel.
  • the amount of small parts with which the transportation channel is supplied can therefore be set with great accuracy.
  • a further improvement can occur if the projections slope obliquely upwards towards the retaining and dividing wall. In this way it is achieved that those small parts which are not to be taken along arrive back promptly and carefully on the sloping collection area and that the small parts are prevented from being left behind and falling down.
  • the longitudinal extension of the gaps is to be a multiple of the longitudinal extension of the projections. Concretely it is preferable if the longitudinal extension of the gaps is three to five times the longitudinal extension of the projections.
  • the strut could be changed each time.
  • a metering plate is joined on to the strut, in particular to the upper region of the strut, on which the gaps are left open and the projections are formed by bending upwards.
  • the metering plate can, for example, be screwed to the strut for ease of changing.
  • the small parts move as easily and automatically as possible from the sloping collection area on to the upper narrow side of the strut when they come to rest on the retaining and dividing wall in the lower operating position of the strut, it is provided, according to yet another development, that in the lower position of the strut the higher edge of its upper narrow side is located approximately at the height of the adjacent end edge of the sloping collection area.
  • the upper narrow side of the strut therefore becomes a continuation of the sloping collection area and facilitates the transition and the alignment of the small parts.
  • the invention also relates to a transportation channel in a device for transporting small parts in the nature of studs, bushes, pins and suchlike which are delivered to an application site from a store, in particular for application in a delivery device according to one of claims 1 to 8, the transportation channel having a receiver profile of such a kind that the small parts are conveyed on the transportation channel sliding substantially in the direction of their longitudinal axis.
  • Transportation channels of this kind are known. In combination with the corresponding automatic transportation devices they serve in automatic assembly to deliver a large number of small parts, including, for example, screws, continuously to the assembly site.
  • a known example is the automatic production of motor vehicles.
  • the transportation channel can be sloping or driven by an oscillating conveyor.
  • the receiver profile in the transportation direction, i.e. its cross-section is often a segment of a circle, the measurement of which approximately corresponds to that of the small part to be transported. The small parts then slide in a kind of flat channel or trough.
  • the known transportation channels work reliably when the small parts to be conveyed have approximately the same cross-sectional shape and measurement over their whole length. Accordingly, the conveying of bushes with hexagonal or circular cross-section is particularly favourable. If, on the other hand, studs are to be conveyed which have portions of very varying diameter, these can no longer slide smoothly in the transportation channel. They then jump around and no longer slide smoothly in the transportation channel. To guarantee troublefree operation it is necessary to build in baffles for sorting the pins into the right position.
  • the earthing studs consist of a shaft with a thread portion and a substantially cylindrical head.
  • the thread portion is covered by a cap with a hexagonal outer shape.
  • This cap which can consist of a plastics material, for example, covers the thread of the earthing stud during lacquering and similar procedures.
  • the round head of the screw protrudes above the hexagonal cross-section of the covering cap, the result is a particularly uneven movement of the earthing studs on the transportation channel and this can cause unpleasant disturbances in the transportation procedure.
  • a compound receiver profile means that it is not determined only by one single geometric shape and by one single defining measurement, as is the case, for example, with a segment of a circle in the nature of a flat trough.
  • a compound receiver profile can, for example, be formed by two circular arcs of different diameter or by a circular arc in combination with a polygonal contour.
  • the cross-section of the receiver profile is composed of at least two basic contours, each of which corresponds to one of several longitudinally differing cross-sectional shapes of the small part to be conveyed. In this way in an individual case particularly reliable guidance of the small part in the transportation channel is possible.
  • the transportation channel according to the invention can be further developed in that the receiver profile of the transportation channel is a segment of a circle starting from its upper side, out of which a segment of a circle of smaller diameter protrudes downwards.
  • the continually conveyed screws then slide with their heads on the segment of a circle of larger diameter starting from the upper side, while the screw shank is guided through the segment of a circle of smaller diameter adjoining underneath. It is soon clear that screws guided in this way are no longer inclined to tumble or jump around, i.e., they avoid transverse movements on the transportation channel.
  • the receiver profile of the transportation channel is a segment of a circle starting from its upper side, out of which a rectangle protrudes at the bottom, the already mentioned earthing studs can therefore be particularly well transported.
  • the cylindrical screw head of the earthing studs which comprises the largest transverse measurement of this small part, then slides in the part of the receiver profile shaped like a segment of a circle, while the covering cap of the earthing stud, which comprises the smaller transverse measurement, engages with the outer part of a hexagonal side of a rectangular part of the receiver profile.
  • the earthing studs, with their longitudinal axis slightly tilted downwards, are then located exactly in the longitudinal axis of the transportation channel.
  • the transportation channel can consist of a longitudinal profile in the nature of a rail, from the upper side of which a longitudinal groove with a cross-section shaped like a segment of a circle starts and continues downwards in a rectangular groove.
  • the transportation channel can also consist of a flat part bent into a longitudinal profile.
  • the reference numeral 1 designates a sloping collection area, on which small parts, in this case earthing studs 15, roll downwards and come to rest on the retaining and dividing wall 3.
  • the retaining and dividing wall has a bent part 4 and an upper edge 3a which runs obliquely upwards.
  • the sloping collection area 1 forms with its bent end part 1a an end edge 2, which is located at a distance in front of the retaining and dividing wall 3.
  • an aperture 5 is thus formed, as can be seen particularly clearly from Figure 4.
  • a strut 6 is perpendicularly displaceable parallel to the retaining and dividing wall 1 (sic) .
  • the strut 6 has the shape of a flat plate, the upper narrow side 6a of which slopes obliquely downwards towards the retaining and dividing wall 3.
  • the obliquely downwards directed slope of the upper narrow side 6a of the strut 6 can be seen particularly clearly from Figures 2 and 4.
  • a metering plate 7 is attached in the upper region of the strut 6. It can be changeably fixed to the strut 6, for example, with screws.
  • the fastening holes 8 serve this purpose.
  • the metering plate extends with its lower part in the direction of the strut. Projections 9 are formed upwardly in the metering plate, pointing obliquely upwards. The projections form gaps 10 between each other. In the upper operating position of the strut 6 its upper narrow side 6a protrudes above the upper edge 3a of the retaining and dividing wall located next to it, as is particularly clear from Figures 3 and 4.
  • the transportation channel 11 On the side of the retaining and dividing wall 3 remote from the strut 6 is the transportation channel 11. It runs parallel to the upper edge 3a of the retaining and dividing wall 3 and thus also slopes obliquely. On the side remote from the retaining and dividing wall the transportation channel 11 has an additional guiding face 19. When in the upper operating position of the strut 6 the small parts slide down from its upper narrow side 6a, the guiding face 19 safely effects that all the small parts actually arrive in the transportation channel 11.
  • the operating method of the delivery device described so far is as follows.
  • the strut 6 travels in stages upwards and takes with it the earthing studs 15 located on its obliquely downwards directed upper narrow side 6a.
  • the upper operating position of the strut is illustrated in Figures 3 and 4.
  • the earthing studs 15 slide in this position, in which the upper edge 6b of the strut is located higher than the upper edge 3a of the retaining and dividing wall, obliquely downwards into the transportation channel 11.
  • This operating method is seen particularly well in Figure 4.
  • the guiding face 19 ⁇ as already mentioned ⁇ prevents the earthing studs from ending up outside, having gone past the transportation channel 11 with particular force.
  • the metering plate 7 with its obliquely upwards directed projections 9 prevents the whole of the upper narrow side 6a of the strut 6 from being used for transportation purposes. On the contrary transportation takes place only in the gaps 10. Surplus earthing studs 15 are rejected by the projections 9 and roll back on to the sloping collection area.
  • the transportation channel 11 consists of a longitudinal profile in the nature of a rail, from the upper side of which the receiver profile 12 starts.
  • the receiver profile 12 has a compound cross-section. It consists of a segment of a circle 13, which starts from the upper side of the transportation channel 1 and to which a portion 14 in the shape of a rectangle adjoins underneath. In this way a longitudinal groove emerges with a cross-section shaped like a segment of a circle, which a smaller rectangular groove adjoins underneath.
  • the small parts to be conveyed here are earthing studs 15, which slide in the receiver profile 12 of the transportation channel 11.
  • the earthing studs 15 consist of a screw bolt with a screwed on covering cap.
  • the screw bolt has a cylindrical head 17 which protrudes above the covering cap with its hexagonal cross-section 16 in a radial direction.
  • the earthing studs 15 slide in the receiver profile 12 of the transportation channel 11, their cylindrical region 17 being guided in the part of the receiver profile 12 shaped like a segment of a circle, while the region with a hexagonal cross-section 16 locates itself in the rectangular part 14 of the receiver profile 12.
  • the earthing studs are fixed securely in a transverse direction and slide evenly in the longitudinal direction of the transportation direction, with their longitudinal axis slightly tilted downwards, as seen in Figure 5.
  • the measurements are herein fixed in such a way that the transverse measurements of the receiver profile are marginally larger than the corresponding regions of the earthing stud to be conveyed.
  • the transportation channel consists of a longitudinal profile in the nature of a rail, which can be produced, for example, by extrusion.
  • the screw holes 18 located on the rail serve to fasten the entire component.
